CULINARY APPARATUS.

Specification forming part of Letters Patent N o. 89,613, dated May 4,1869.

To all whom it mag/concern:

Be it known that I, BENJAMIN WARDWELL, of the city and county ofProvidence, and State of Rhode Island, 11a-ye invented a new and use fulImprovement in Boilers for Culinary Purposes 5 and I do hereby declarethat the following is afull, clear, and exact description of the same,reference being had to the accompanying drawings, makin gpart of thisspecification, in Which- Figure lis a vertical section of my improvedboiler or culinary apparatus. Fig. 2 is a perspective view of theimproved portion of the same.

Similar letters indicate corresponding parts in both the figures.

I y invention consists in constructing the boiler with a chamber beneathand around the pit or portion which enters the hole in the stove-plate,so that the steam which is generated by the culinary process may beconveyed through a suitable tube, extending fromthe top of the boilerinto the said chamber beneath, and thence escape into the stove orchimney instead of into the stove-pipe or into the room, as heretofore.A

In the drawings, A is the boiler, such as is lordinarily used uponastove, the top plate of which is represented bythe lines marked Dv D inFig. l, for general culinary purposes. Upon one side of the walls of thesaid boiler there is cast or otherwise formed a tube, G,.

opening near the top into the interior of the boiler, to receive thesteam and fumes generated in the vessel, and opening at the bottom intothe recess or chamber E, which may be formed beneath the bottom of' theboiler by extending the walls or shell A of the boiler below the bottomsurface of the same to the extent, say, of three-eighths of an inch.This, it will at once be seen, elevates the bottom of boiler fromcontact with the stove-plate D, upon which it rests while in `use overthe tire, and thus affords a space, E, between the said bottom andstove-plate, into which the steam may be conducted by a tube like Grfrom the top of the boiler, so that the steam Will escape into the stoveas fast as it is generated, at the same time furnishing a greater resurface on the bottom of the boil--r than is possible with the bottom ofthe boiler resting at and closely upon the stove-plate, as in theordinary construction of such boilers and apparatus, Which exposes tothe action of the lire only so much of the pit L as extends beneath thestove plate within `the boiler-hole.

Separately the tube G for conducting the l steam from the top to thebottoni of the boiler is not claimed..

' Ola/im.

A boiler for culinary purposes made substantiallyin the manner hereindescribed, so that there shall be a space or chamber, E, formed betweenthe bottom of the boiler and the stove-plate, into which the steampassing from the boiler through the pipe or conduit Gr is discharged, asand for the purposes shown and set forth.

In testimony whereof I have signed my name to this specification beforetwo subscribing witnesses.
